Xavi believes the Seleccao are not to be underestimated and praised a number of the midfield threats that will line-up for Paulo Bento's team.

"They’re a great side," Xavi told Fifa.com. "Not just Cristiano, who’s an attacker you constantly need to keep an eye on, of course, but Nani as well and good footballers like Joao Moutinho and Raul Meireles.

"They're both very skilful and can move the ball around quickly. They’re a tough team and, on top of that, they're very tight at the back very well. It’s going to be tricky."
